README.md

Run git config --global alias.save-branch '!~/scripts/git-save-branch.sh (customize the path to match where you save the script to)

Now you can run git save-branch to run the script

git-save-branch.sh

#!/bin/bash

CURRENT_BRANCH=$(git rev-parse --abbrev-ref HEAD)

if git diff --exit-code; then
    echo "Clean dir";
else
    echo "Error: git diff reports non-clean directory";
    exit 1;
fi

find_new_branch_name()
{
    branch_name=$1
    suffix=$2
    new_branch_name="$1-$2"

    if [ "$suffix" -ge 5 ]; then
        exit 1;
    fi

    if git rev-parse --quiet --verify "$new_branch_name"; then
        next_suffix=$((suffix + 1))
        find_new_branch_name "$branch_name" "$next_suffix"
    else
        git branch "$new_branch_name"
        echo "Created new branch $new_branch_name"
